Just a quick page create to let everyone know I still peruse Robocode on occasion. I'm happy to see DustBunny and Infinity doing their things, and Moebius getting stomped :)
My Bots:
Uh oh, I think I just figured out how to completely cheat the codesize thing. I could probably fit all of Toorkild's code into a nanobot. How? Running Java Byte code from a static buffer. Take any robot's byte code and drop it statically into an array/string/whatever. Array values do not count towards size. Write a routine that jumps the code pointer into the array. You are now running a nearly infinite amount of code without a major size hit. I could probably write a bot like this in an evening if I really wanted to cheat and win this badly. Thoughts? --Miked0801 01:02, 28 May 2009 (UTC)
- Oy! Not sure how we'd deal with that. I wonder if Robocode's classloaders could prevent this from happening? Or the code size utility produce some kind of "N/A" code size for classes that do this? --Voidious 02:56, 28 May 2009 (UTC)
- I'm fairly sure the Robocode security manager wouldn't allow this, I once tried using Java Reflection and the security manager disabled my bot immediately. However, if it is possible, I think we should either 1) modify the Codesize util so it looks for bytecode in strings as well or 2) fix the security manager so that it isn't possible to jump the code pointer into a static buffer. But why don't you try it and see if it works =) --Skilgannon 09:19, 28 May 2009 (UTC)
